LIQUID-LEVEL INDICATOR.

Application led August 28, 1924. Serial No. 734,782.

rIhis invention relates to gages and more particularly to gages whereby the quantity in an enclosure .is made known of liquid through the buoyancy of a float on the inside, acting on a scale on the outside.

The general object of my invention is to provide a simple, ineX gage that will always b Reference is to be ha pensive, non-fouling e. dependable. d to the accompanying drawings forming a part of the specilication, it being unders tood that the drawings are merely illustrative of oneembodr nient of the invention.`

Figure l is a frontembodying my inventio elevation of the gage Figure 2 is a side elevation of the gage illustrated in Figure l.

Figure 3 is a detail view of the indicator and means for actuating same.

A roller Hoat a is and c. Drums Z2 and have the leads d are attached t greater circumference.

VIntermed lesser circumference and late drum c has a its single lead d is attached to the gage indicator on the one hand and -to the. drum The gage indicator itse top of the tank t. The

The

ancy. In operation the lead d unravels sutliciently far, depending on the amount of liquid in the tank, to give the pointer t of the gage indicator a displacement along the scale j' substantially proportional to the height of thecontained liquid.

VThe advantages of a gage of this kind as described herewith are the few parts used,

the directV leads to the scale, and the elimination of guides necessary to maintain the float in position. f

Having described my invention I claim: l. In combination with a tank and a spring pressed gage indicator mountedon said tank, a roller float within said rtank having winding drums, two of large and one of smaller diameter, winding leads two severally attached to the two large drums and both attached to the bottom of said tank and another lead attached to the smaller drinn .and to said gage indicator tov f actuate said gage indicator.
